What your wife did was probably a manufacturer’s reset to original factory drive image (completely overwrites the drive with an image of the original from a hidden partition).
If that’s what happened, the data is gone (except for a professional recovery service). Here’s a link to the only one that I know has been around for a long time, is professional, & should be able to reconstruct your drive. It will cost several hundred $ or more. Only you can determine if it’s worthwhile.
Good Luck

Thanks, RT. I’ll see if the wife wants to do it.
